      Drew ByrdSep 12, 2025
      If the string voltage on your SolarEdge Inverter is not 0V but lower than the number of optimizers, it could be due to: * Power optimizers not connected in the string. Connect all power optimizers. * Modules not connected properly to power optimizer inputs (not applicable to smart modules). Connect the modules to the optimizer inputs. * String reverse polarity. Check the string polarity using a voltmeter and correct if needed.
